<p align=LEFT> <A HREF="doll7.html"><img src="fig/h6.gif" alt="doll6"></a> How does it move like a real server walks? The motion of a pair of plates asymmetrically attached to each side of the driving wheel looks like alternately moving legs. The back and forth motion of the legs results from a crank mechanism. The legs move alternately along with a pair of plates attached to each side's driving wheel. As the two plates are attached oppositive to each sides driving wheel, they move individually separate from the crank mechanism linked to each leg of the doll.
